I found this quite interesting. Small multiples, also called as panel charts, are a powerful way to depict multidimensional data and bring out insights. They are easy to read too.
So, today, let us learn how to create such charts using Excel.
Step 1: Arrange your data
Almost any chart or visualization worth its salt must begin with proper arrangement of data. Since I could not get the data for the unemployment chart, I made up a few numbers for a fictional Confectionery Company. The data is shown below.
So, we have the data for years 2007 thru 2010, for the regions – South, West & North and for the product lines – Chocolates & Biscuits
Step 2: Select Products for one region & make an area chart
This is simple. Just select data for chocolates & biscuits for one region and make an area chart. You should have something like this:
Step 3: Resize the area chart & format it
Now, we need to make this area chart closer to what we want.
- Select the bottom area series and fill it with white color.
- Now resize the chart so that we can fit 3 of them in the area you got.
Step 4: Add same data to the chart
Now, select the same region data, press CTRL+C to copy it. Select the chart and paste it by pressing CTRL+V. See below demo to understand how to do this.
We are doing this because we want to have lines with markers on our chart. But the area chart lines cannot show markers. So we are going to add the same data one more time, but this time format it to be shown as a line.
Step 5: Select the new series and format them as line charts
Select each of the new area series and format as line chart with markers.
You should have something like this at the end.
Step 6: Format the chart
This is where you unleash the creativity. In order to match the look of NYTimes chart, here is what you can do.
- Set the fill color between lines to something dull.
- Format 2 lines in distinct colors.
- Format gridlines & axis lines to something dull.
- Set axis maximum to 25 (as all charts in small-multiples should have same axis settings)
- Set axis major unit to 5.
Step 7: Repeat this for other regions
Now, just copy and paste this chart a couple of times. Just adjust the data source so that we have new charts using this technique.
Note: Learn how you can add descriptive labels to charts.
That is all. You just made a small multiples chart that looks awesome. Congratulations.

Do you use Small Multiples or Panel Charts?
I really love to use small multiples or panel charts whenever I am analyzing data or presenting results of the same. They offer excellent value per pixel. That said, they take some time to construct. Also, you must tweak axis settings and plot area to get the perfect result. That is why I prefer the in-cell variation of these charts. They are quick to setup and easy to wow (for more on these techniques, see below).
